"We do not sell, trade, or otherwise transfer to outside parties your Personal Data unless we provide users with advance notice. This does not include other parties who assist us in operating our app, conducting our business, or serving our users, so long as those parties agree to keep this information confidential. However, non-personally identifiable visitor information may be provided to other parties for marketing, advertising, or other uses."
While personal data isn't sold, the policy carves out a broad exception for sharing 'non-personally identifiable' information with unspecified third parties for marketing, advertising, or any other use — with no opt-out mechanism mentioned.
